Me thinks: If your goal is to replace 200000+ mileage suspension parts, and to do it with a good and proven product without paying through the nose, I would go with Eibach springs and KYB shocks. The Eibach set of 4 springs is not really that expensive. They are called lowering springs, but are quite a bit firmer and don't sag so much under load, so it doesn't bottom out as before. There is not much lowering from them, but are so much firmer and therefore better on bad roads. The KYB shocks, especially the more recent sort, are also a bit firmer than the OEM. Compared to a softer 2015 style suspension with 200 000miles, that should be a huge improvement. Compared to OEM part prices, it is also beneficial for your wallet!
The parts you mentioned are very much more pricey. In these parts and probably in Canada too, for that much $$$ you could get an entire and perfectly useable old used car. Like I said, it all depends on what you want.
